v0.6.1 UX polish and bugfixes

[0.6.1] — 2026-07-03

UX polish on top of v0.6.0, plus real correctness fixes found while building
it: a consistent color palette for Threshold Colors, a resizable style
dialog, a silent data-loss bug in entities-row threshold parsing, and a
card_mod:/uix: duplication bug reported after v0.6.1's own initial release —
this changelog entry covers everything that shipped under the v0.6.1 tag.

Added

• Color palette for Threshold Colors — cms-color-picker gained a
  compact mode: a small swatch button that opens a popover with the same
  10-color preset palette already used by Icon Color, plus a raw hex/var()
  text field. Used for every threshold rule's color and the default color,
  at both the card level (cms-threshold-module) and the entities-card
  row level (cms-entities-rows-module), so a consistent palette is always
  one click away instead of hunting down hex values to reuse. The popover is
  position: fixed and clamps to the viewport so it can't render off-screen
  or get clipped by an ancestor's overflow: hidden.
• Threshold parser accepts palette var(--x-color) values —
  parseThresholdJinja's rule/default regexes now recognise
  var(--red-color)-style tokens (not just hex), so a rule picked from the
  palette round-trips back into a recognised rule instead of falling through
  to Advanced CSS.

Fixed

• Style dialog no longer stays pinned to a short card's height when you
  open Style. Editing a card with few controls (e.g. a tile card) made
  HA size the dialog to fit that short content; switching to the Style tab
  didn't grow it, forcing constant scrolling through a long module list in a
  cramped window. Root cause was two-fold: HA's dialog migrated from
  MDC/MWC to a "Web Awesome" wa-dialog wrapping a native <dialog>, so the
  legacy --mdc-dialog-max-height custom property no longer reaches the
  element that actually controls sizing; and hui-card-element-editor is
  display: inline by default, on which min-height is a CSS no-op. Fixed
  by setting max-height directly on the native <dialog> (reached through
  two nested shadow roots) and switching the card editor host to
  display: block before applying min-height. Verified empirically
  against a live HA instance — both fixes were necessary; neither alone
  resolved it.
• Entities-row threshold default color was silently discarded on every
  re-open of the panel. _parseEntityRowCss's value-extraction regex
  ([^;}\n]+) excluded } from the captured value, which truncates any
  Jinja {{ ... }} expression right before its closing }} — the rule
  conditions still parsed correctly, but the trailing else '<default>'
  was cut off, so the default color silently fell back to the hardcoded
  #888888 instead of the value the user actually configured (e.g. a
  palette var(--grey-color)). If the user then touched anything else on
  that row, the wrong default got written back into their YAML. Fixed by
  replacing the ad-hoc regex with the existing Jinja-safe parseCss (the
  same parser already used for card-level CSS), reused via a new exported
  parseEntityRowCss in state-mapper.ts — which also makes this path unit
  testable for the first time (9 new tests in test/parser.test.ts).
• Editing an already-styled card left a stale duplicate of the other
  key's content sitting alongside the new one, instead of consolidating to
  a single source of truth. Reported: a card styled under card_mod:
  from before UIX was installed, edited after switching to UIX, ended up
  with both a new uix: block and the old, now-dead card_mod: block
  still present. On open, the panel now merges settings from both keys
  (not just whichever resolveStyle() would pick) when both carry real
  content, so a setting that only lives under the currently-inactive key —
  left over from switching engines, or from editing each key separately —
  isn't invisible to the editor or silently dropped on the next save
  (mergeStudioStates / mergeEntityRowStyles in state-mapper.ts, wired
  in via cms-panel.ts's _buildMergedState). On save, applyCardModStyle
  now writes the merged result to the active key and clears the other
  key's .style — rename instead of duplicate when only one side had
  content, consolidate-and-clear when both did — rather than leaving it
  stale or syncing it forever. A uix: block using macros/billets is still
  never touched (can't be safely parsed into recognised state or determined
  redundant), matching the existing untouchable-content rule. The distinct
  "Copy to card_mod" fix button (for when neither engine can be confirmed
  installed) now has its own implementation that copies uix.style into
  card_mod.style verbatim and deliberately leaves uix.style alone —
  it's a defensive fallback-add, not a settings edit, so the new
  clear-the-other-key behavior doesn't apply to it.
• A style with the same selector declared twice — e.g. a static default
  in one ha-card { } block, later overridden by a conditional value in a
  second ha-card { } block, a common hand-edited pattern — silently lost
  the second (actually live) declaration entirely, not even preserving it
  in Advanced CSS. findTarget/findProp only ever looked at the first
  matching selector, and the "unclaimed → Advanced CSS" reconciliation keys
  purely on selector+property strings, so the second block's property
  collided with the first's claim key and was dropped without ever being
  read into any module's state. parseCss now coalesces same-selector
  blocks (and de-duplicates repeated properties within one block) using
  real CSS cascade semantics — later declaration wins — before any
  recognizer runs, matching what actually renders. Found via a real
  user-reported card that used exactly this pattern for a threshold
  override; both the coalescing itself and the merge fix above are needed
  to correctly round-trip that card (5 new tests in test/parser.test.ts +
  test/generator.test.ts, plus a dedicated test/merge-dedup.test.ts and
  a new live sandbox check, tools/sandbox/harness/merge_check.mjs,
  covering both fixes against a real UIX instance).
